About PIK3AP1

Predicted to enable phosphatidylinositol 3-kinase regulatory subunit binding activity and signaling receptor binding activity. Predicted to be involved in positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; regulation of inflammatory response; and regulation of innate immune response. Predicted to be located in membrane. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Jul 2025]
